+.Synopsis
+    Imports a the annotations from a source CSDL file into the target CSDL file.
+.Description
+    Leverages basic XML parsing capabilities to import annotations from a source CSDL file into the target CSDL file.
+    Will NOT handle deduplication of annotations, so if the target CSDL file already has annotations, they will be duplicated.
+    This script is intended to be used in the context of the msgraph-metadata repository.
+.Example
+    ./scripts/copy-annotations-to-csdl.ps1 -sourceCsdlPath C:/github/msgraph-metadata/schemas/annotated-v1.0-Prod.csdl -targetCsdlPath C:/github/msgraph-metadata/schemas/annotated-v1.0-Prod.csdl
+    ./scripts/run-metadata-validation.ps1 -repoDirectory C:/github/msgraph-metadata -version "v1.0"
+.Example
+.Parameter repoDirectory
+    Full path the the root directory of msgraph-metadata checkout.
